description=This large Napoleon wrasse (Cheilinius undulatus) has grown used to handouts from divers. It uses its extensible jaws to suck up food. Most wrasses and parrotfishes are examples of Åsequential hermaphroditism,Å in which a fish changes sex in a predictable fashion. Females can change sex into brilliantly colored males, known as terminal males or supermales. This particular wrasse is four feet in length.ìÄ ìÄLocation: Red Sea. ìÄ
